Abstract: PURPOSE:To enable to form in a short time a smooth hole having roundness in a compound semiconductor substrate by a method wherein after the compound semiconductor substrate is etched according to an etching liquid stirred relatively, etching is performed by stopping stirring of the etching liquid. CONSTITUTION:A stirring rotor 13 is rotated, and a compound semiconductor substrate 1 is immersed in an etching liquid 11 in the condition stirring the liquid 11. The substrate 1 thereof is covered with an etching-resistant film leaving a hole forming part. At this time, the liquid 11 flows and circulates continuously without stagnating, a reaction is advanced as a reaction rate-determining process, and reaches the prescribed objective depth in a short time. The shape of the hole is made in a squarish condition like a hole 14a at the point in time thereof. Stirring of the liquid 11 is stopped at a point in time when the reaction reached the prescribed objective depth thereof. Thereupon the process is transferred to a diffusion rate-determining process, and the shape of the hole is regulated to a hole 14 having the rounded corner parts. Accordingly, the smooth hole having roundness is formed in a short time, and productivity is enhanced.

IPC: G11B5/127
Filed: 1985-05-07
Abstract: PURPOSE:To maintain the satisfactory magnetic characteristics between a main magnetic pole and an auxiliary magnetic pole, by having a biased section form of the auxiliary magnetic pole at the winding part of an energizing coil so that the size of said section is increased only in the direction where the magnetic fluxes are easily collected from the main magnetic pole. CONSTITUTION:An auxiliary magnetic pole 20 is set opposite to a main magnetic pole 10 with bias secured at the downstream side of the traveling direction of a recording medium RM. At the same time, a groove D is formed to the pole 20 at the downstream side of the traveling direction of the medium RM and at the position near the center of the pole 10. Therefore the section area of the pole 20 is reduced at least at the winding part of an energizing coil 30 by an amount equal to a counter area of the groove D to the pole 10. As a result, the inductance of the coil 30 is reduced by a due amount. However,the magnetic characteristics have no deterioration at all between both poles 10 and 20.
